More and more of the
electronic gadgetry and other pieces of equipment get mobile and
accompany us wherever we go. But whenever you travel in the open,
you hardly ever know where and when you get the chance to charge
your devices again. Stop being concerned by the power cuts –
take the PowerTank XXL along with you and enjoy your little
electronic helpers to the fullest!

The
philosophy behind the PowerTank
XXL
Whoever
deals with several or larger electric consumers finally learns
the fact, that their portable power supply quickly comes up
against its limits. The main point about this subject may be the
manufacturer’s misunderstanding of basic mobile power supply
issues, or even the euphemistic behaviour to assure customers of
device features, that simply can’t be realized on a physical
basis. This is usually the time when a manufacturer comes up
with “volts”, “ampere” and “watt-hours” blending
them to facts John Doe can’t (and need not to) follow.
SIStech
is not about to present you the perfect solution on that issue,
because we believe, that there is no perfect solution yet.
SIStech is about to offer you the best compromise possible so
far.
And
that’s how it looks like for the PowerTank XXL:

Dimensions and weight
This
is probably the greatest trade-off, because a portable power
supply has to deal with narrow acceptance limits regarding size,
weight and energetic output. By performing extensive field tests
SIStech finally made it to discover acceptable limits and
decided to give the PowerTank XXL the dimensions and weight
similar to a large chocolate bar (7.8 x 26.5 x 2 cm / 570 gr).

Output rating
We
had to draw a line between acceptable and unacceptable electric
consumers by defining netbooks as suitable and lightweight
companions on the move and considering bulky laptops/notebooks
as not relevant for that issue. Laptops usually demand a power
input of up to 120 watts / 7 ampere, but this is in no way
compatible to small and lightweight power supply units. Besides,
there is no point to drag around heavy laptops if you can have a
dirt cheap netbook for the most tasks you may need to perform on
the road. Netbooks take around 40 watts and the ultramodern
netpads that recently started flooding the market demand
incredible 10 watts only.

Power output / electrical connection ports
Except
for Laptops almost any mobile gadget can be powered or charged by
the PowerTank XXL. For some of them you may need the peripherals
provided. From now on you can have easy-to-use and highly
adaptable access to more power for your netbook, iPad, webpad,
iPhone, iPad, mp3-player, navigation system, digicam, camcorder,
cellphone, illuminant, small battery charger or whatever portable
gadget you may have to power or charge.
Two
independent power outputs offering an 12-15 volts power socket (cigarette
lighter socket) as well as an standard 5 volts USB socket make
sure that you can handle a high variety of devices. Of course,
both of the standalone sockets can be used the same time.

Recharging process / power input
As
long as you have a constant current- as well a constant voltage
feed, it is not a big deal to charge lithium ion accumulators by
using appropriate recharge electronics. Once you have to rely on
fluctuating current and varying power input conditions as it is
the case while charging the PowerTank by a solar panel, the
recharge job gets virtually impossible to be carried out.
To
help solving that problem SIStech developed the new DPS
electronics (Digital Power Scan). It’s a system that
continuously analyzes the ongoing power input and adapts the
recharge process to the measured values. Combined with the MPPT
(Maximum Power Point Tracking) technology the PowerTank XXL is
capable of a quick and appropriate self-recharge at a mains
voltage as well as a (slower recharging) solar cell to its full
capacity.
